Abstract: Provided is a variable displacement swash plate type compressor including: a lug plate fixed to a driving shaft; and a swash plate combined to the lug plate and whose tilt angle is varied according to rotatory motion, wherein the lug plate includes a protruding portion protruding towards the swash plate, and a rotatory power projection transmitting power for rotating the swash plate is formed at a leading end of the protruding portion through the swash plate. Accordingly, a varying operation between a maximum tilt angle and a minimum tilt angle of the swash plate and a rotatory power transmitting operation for rotating the swash plate are performed at different locations, thereby simultaneously improving the varying operation and the rotatory power transmitting operation of the swash plate.
